STRUCT TEGRA_VI_OPS(9)

✨ struct tegra_vi_ops — Tegra VI operations ✨

okay so bestie, welcome to the struct tegra_vi_ops(9) page from the Kernel API Manual 💅 this is literally the little bundle of function pointers that tells the Tegra VI driver how to actually do stuff, and we're gonna walk through every single one of them. no skips, no shortcuts, no cap 🫶

🌸 NAME 🌸

struct tegra_vi_ops — the Tegra VI operations, aka the vibe check for your video input peripheral 👑

---

🦋 SYNOPSIS 🦋

here's the whole struct, bestie, copied exactly so you can trust it:

struct tegra_vi_ops {
    int (*vi_enable)(struct tegra_vi *vi, bool on);
    int (*channel_host1x_syncpt_init)(struct tegra_vi_channel *chan);
    void (*channel_host1x_syncpt_free)(struct tegra_vi_channel *chan);
    void (*vi_fmt_align)(struct v4l2_pix_format *pix, unsigned int bpp);
    void (*channel_queue_setup)(struct tegra_vi_channel *chan);
    int (*vi_start_streaming)(struct vb2_queue *vq, u32 count);
    void (*vi_stop_streaming)(struct vb2_queue *vq);
};

look at it. it's giving "soc abstraction done right" 😭✨

🎀 Members 🎀

• vi_enable — the soc-specific operations you need to enable/disable the VI peripheral. think of it as the on/off switch, but make it per-soc 🌈
• channel_host1x_syncpt_init — initialize synchronization points ✨
• channel_host1x_syncpt_free — free all synchronization points 🦋 (yes, all of them, clean up after yourself, bestie)
• vi_fmt_align — modify pix to fit the hardware alignment requirements and fill image geometry. it literally tells your pix format to sit up straight and match what the hardware expects 💅
• channel_queue_setup — additional operations at the end of vb2_ops::queue_setup. just a little extra somethin' at the finish line 🎀
• vi_start_streaming — starts media pipeline, subdevice streaming, sets up VI for capture and runs capture start and capture finish kthreads for capturing frames to buffer and returns them back. main character energy fr fr 🔥 it's doing a lot
• vi_stop_streaming — stops media pipeline and subdevice streaming and returns back any queued buffers. the graceful exit, iconic 👑
